Poll: The crazy crap Americans believe

1 / 50

Back to Gallery

Known for its niche polling, the Public Policy Polling outfit explored the crazy crap Americans believe (OK, sorry to anyone who believes one or all of these conspiracies) … and published its results Tuesday.

“On our national poll this week we took the opportunity to poll 20 widespread and/or infamous conspiracy theories. Many of these theories are well known to the public, others perhaps to just the darker corners of the internet,” they said.

PPP surveyed 1,247 registered voters with a margin of error of plus or minus 2.8% for this poll. The survey was conducted March 27-30.

About 90 million Americans believe aliens exist. Some 66 million of us think aliens landed at Roswell, N.M., in 1948. These are the things you learn when there's a lull in political news and pollsters get to ask whatever questions they want.
